I asked about oil in the radiator of a 9N last fall and was told that it was a cracked block or a head gasket. I had nether need nor time to follow up and take it apart after that but I was thinking that the 9N is a flat head and there are no oil channels in the head so it would probably be a cracked block. The amount of oil is not great and there is no water in the oil. I looked up previous conversations on this subject and the idea of combustion products pushing through into the coolant seemed sound, as well as a lot cheaper then a cracked block. I could not see any combustion gas bubbling up into the radiator when it was running but could not check under load. Last week I removed the head, it had a metal head gasket and I could not easily tell if it was leaking. On cleaning the head I found that there was some pitting in areas that would be in full contact with the gasket and on putting a straight edge on it I could tell that it is a tad warped as I could see light under the edge over the number 2 and 3 combustion chambers. How much warping can you have on a head? Will it torque down level? I am tempted to send it out and have it machined flat. Should I? I have noticed that there are two kinds of head gaskets available for this tractor. Which one is best?
I know you guys have all the answers, so thanks in advance.

I don't know if there's a flatness number in the FO4 or not. A typical number for a car or truck is somewhere around .005-.008 max on the diagonal. Sometimes a little more - some times a little less. You need a good straight edge (machinist) and a CLEAN head surface to measure those kinds of clearances accurately.

HTH,

It's a thin head.. -some- warp wil probably 'bolt' out.. However.. for 150$ you can just get a new haed and be sure. As for shaving it.. keep in mind that there is very little 'meat' that can be shaved off. if it's been shaved once already.. it's toast.

I'd personally try the fiber gasket. it's a tad more forgiving. If I thought there was a shaving issue.. and didn't have 150$.. I'd use 2 fiber gaskets... that's an old shade tree trick. it's certaintly not ideal.. but I'd wager there are more than a few N's runnging around with stacked headgaskets..
